BICYCLE-LAM P.

SPECIFICATION forming part of Letters Patent No. 594,516, dated November30, 1897.

Application filed February 25, 1896. Serial No. 580,701. (No model) Toall whom it may concern.-

Be it known that I, GLAUDIUs V. BOUGH- TON, a citizen of the UnitedStates, residing at Bufialo, in the county of Erie and State of NewYork, have invented certain new and useful Improvements in Bicycle-Lampsand I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to figures of reference markedthereon, which form a part of this specification.

My invention relates to improvements in lamps which are speciallyadapted for use upon bicycles. r

The object of my invention is to provide an improved lamp which isparticularly constructed for carrying an improved taper which forms thesubject-matter of an application filed by me on the 25th day ofNovember,1895.

To that end my invention consists of certain details of construction,all of which will be fully hereinafter described, and pointed out in theclaim.

In the drawings, Figure 1 is a side elevation, and Fig. 2 is a frontelevation, of my improved lamp complete. Fig. 3 is a rear elevation ofthe same with the back portion of the reflector removed. Fig. 4 is acentral Vertical section. Fig. 5 is a top plan view. Fig. 6 is an'underside View with the taperholder removed. Fig. 7 is a detached detail viewof the under side of the cap and depending deflector. Fig. 8 is a sideelevation of a special form of spring-socket for carrying the lamp. Fig.9 is a central vertical transverse section of the spring-socket. Fig. 10is a top plan View of the spring-socket, and Fig. 11 is averticalsection taken on the line a; m of Fig. 10.

Referring to the drawings, it will be seen that the hollow casing orshell has the configuration of two intersecting cylinders, of which 1 isthe vertical and 2 is the horizontal. Upon one side of the horizontalcylinder 2 is an elongated opening 3, covered by a stationary frame 4,in which is set a piece of red glass 5. On the opposite side is asimilar opening 6, and 7 is a loose frame also carrying red glass 8 andadapted for vertical adjustment in the ways 9 9 to cover the opening 6,as shown in Fig. 1, or to be slid vertically away from the same topermit of the insertion of a match to light the lamp. At the lower endof cylinder 1 is the removable taper-holder 10 with bayonet-joint 11 forholding it in place.

12 12 are the arms of a bracket, their inner ends being riveted to thecylinder 2 along its intersection with cylinder 1 and their outer endscarrying a vertical socket 13 with clamping-screw 14 for securing it tothe frame of the bicycle. Just under the arms 12 12 and in the cylinder1 are the draft-holes 15. The lower wall of the cylinder 2 within itsintersection with the cylinder 1 is provided with the central opening17, through which the flame ascends. Surrounding this opening are thedraft-holes 18.

The upper end of the cylinder 1 is provided with the annular enlargement19, in the under wall of which are the series of draft-holes 21. Uponthe side wall of this enlargement 19 are a similar series of draftholes22. A cylindrical deflecting-wall 23 rises above the level of thedraftholes 21, as clearly shown in Fig. 4:-

24: is a flanged removable cap fitting down snugly upon the enlargement19, and 25 is a deflector formed of a convex disk and depending from arod 26, centrally secured to the cap 24. This deflector extends downbelow the level of the line of draft-holes 21 in the under wall 20 ofthe enlargement 19.

The front end of cylinder 2 has an annular enlargement 27, within whichis secured the conical reflector 28, its inner smaller end being cutaway at top and bottom, as at 29 29, for the upward passage of theflame. The rear end of the cylinder 2 is provided with the flangedremovable concave reflector 30. A glass 31 is secured across the conicalreflector 28. Upon the upper and lower side of the inner wall 32 of theannular enlargement 27 are the draft-holes 33, and just under and overthese holes 33 and in the conical reflector 28 are similar draft-holes34. These draft-holes 33 and 341. permit a passage of air across theinner face of the glass 31, which prevents an accumulation of moisturethereon.

. The special form of spring-socket shown in Figs. 8, 9, 10, and 11 isconstructed as follows:

36 are arms similar to the arms 12 12 (shown in Figs. 1, 4C, 5, and (i)and are secured to the sides of the lamp in the same manner and at th esame points as the arms 12 12. The outer ends of the arms 36 36 arepivoted to the end walls of the socket 37, as at 38. The rear face ofthe socket has the outwardly-extending rcccss 30, adapted for the loosereception of the nut 40, with which the thumb-bolt 41 is inscrew-threaded engagement and by means of which the lamp is secured tothe frame of the bicycle. L2 is a leaf-spring with its ends curved inopposite directions, its outer end 4.3 being rigidly secured to the rearface of the socket 37 and its inner end ti being loosely bent around thecross-bar 45, which extends across between the two arms 36 \Vith thisimproved construction the jarring of the bicycle in passing overinequalities in the road is neutralized in a most effective mannerwithout affecting the steadiness of the lamp, thereby precluding thepossibility of extinguishing the lamp by any sudden and violent joltcommunicated from the machine through the arms 36 36.

A taper or lamp is placed in the holder 10, which is then adjusted inposition, as shown in Fig. 1. The taper or lamp can be lighted beforebeing placed in position or afterward with a lighted match insertedthrough the opening 6, the frame 7 having been pushed up for thatpurpose. The draft of air for supporting combustion enters through holes15 and passes up and around the flame through holes 18.

The exits for the draft are through holes 19 21 and the circular seriesof holes in the cap 24:. The cylindrical wall 23 serves to deflect theair entering through holes 21 and conduct it upwardly for egress throughholes 22 and Should air be forced in through holes 21 or 22, as mighthappen while riding at great speed or against a high wind, the dependingconvex disk 25 will deflect it equally to the sides of the cylinder 1and thereby prevent any concentration of the same against the flame ofthe taper or lamp. The arrangement of the conical reflector 2S and rearconcave reflector 30, as shown, practically produces a parabolicreflector, and the concave reflector being removable permits of itsreflecting-surface being readily cleaned and polished when necessarywithout disturbing the light.

I claim- In a bicycle-lam p, the combination with the socket 37 forsecuring the lamp to the frame of the bicycle, of the arms 3U, 3U,rigidly scoured to the body of the lamp at their forward ends andpivoted to the socket 37 at their rear ends and the spring 4.2 with itsends curved in opposite directions its outer end 4-3 being rigidlysecured to the rear face of the socket 37 and its inner end beingloosely bentaround the cross-bar i5 which extends across between the twoarms 3 In testimony whereof I have signed my name to this specificationin the presence of two subscribing witnesses.
